Between 11 and 16 inches could accumulate across southwestern Connecticut.

More snow is likely on Monday, mainly before 9 a.m., according to the weather service.

Winds could gust as high as 55 miles per hour and on average will be around 20 to 35 miles per hour.

In the northern areas, snowfall will begin Sunday afternoon and accumulation could be between 8 to 12 inches. Winds could gust as high as 45 miles per hour.

The National Weather Service warning states that there will be "extremely dangerous travel conditions," with the strong possibility of snow drifting and blowing due to the high wind. Visibility could be near zero with whiteout conditions expected.

The strong winds could take down power lines, tree limbs and could turn Christmas decorations into flying projectiles, so take precautions in advance.

"Do not travel," forecasters warn. "If you must travel, have a winter survival kit with you. If you get stranded, stay with your vehicle."
